The sun delivers 103 W / m 2 of electromagnetic flux to the earth's surface. The total power (in kW ) that is incident on a roof of dimensions 8 m × 20 m is (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

P=I × A=103 × 8 × 20 =16 × 104 W

Q. The sun delivers $1 0^{3} W / m^{2}$ of electromagnetic flux to the earth's surface. The total power (in $kW$ ) that is incident on a roof of dimensions $8 m \times 20 m$ is

$P = I \times A = 1 0^{3} \times 8 \times 20$
$= 16 \times 1 0^{4} W$

Q. The sun delivers 103W/m2 of electromagnetic flux to the earth's surface. The total power (in kW ) that is incident on a roof of dimensions 8m×20m is

P=I×A=103×8×20 =16×104W

Q. The sun delivers $1 0^{3} W / m^{2}$ of electromagnetic flux to the earth's surface. The total power (in $kW$ ) that is incident on a roof of dimensions $8 m \times 20 m$ is

$P = I \times A = 1 0^{3} \times 8 \times 20$
$= 16 \times 1 0^{4} W$
